ABSTRACT
Objective:To study the effect of visceral fat area (VFA) on postoperative complications and pancreatic fistula in patients undergoing laparoscopic assisted radical gastrectomy for gastric careinoma.Methods:Clnical data of 214 primary gastric cancer patients undergoing laparoscopic assisted radical gastrectomy between Jan 2017 and Jan 2022 at the Department of General Surgery, Shouguang People's Hospital were retrospectively reviewed.Results:There were 85 patients in high VFA group and 129 patients in the low VFA group. The body mass index (25.1±3.4) kg/m 2 and visceral fat area (143.4±41.1) cm 2 in the high VFA group were higher than those in the low VFA group (21.2±2.9) kg/m 2 and visceral fat area (58.7±31.9) cm 2. The operative time was (228.3±53.1) min vs. (206.3±62.9) min ( t=5.538, P=0.017). The intraoperative blood loss was (264.6±173.6) ml vs. (213.9±156.2) ml ( t=3.373, P=0.035). The postoperative hospital stay was (12.5±4.0) d vs. (10.3±3.7) d ( t=7.781, P=0.013). Twenty-three cases developed postoperative complications in the high VFA group vs. 20 cases in the low VFA group ( χ2=4.261, P=0.039). Patients in the high VFA group had an incidence of clinically relevant pancreatic fistula of 10.6% vs. 3.1% in patients in the low VFA group ( χ2=5.034, P=0.038). Univariate and multivariate analysis of clinically relevant pancreatic fistulas in patients with different VFA groups showed that men ≥134.6 cm 2 and women ≥91.1 cm 2 with VFA and operative time ≥250 min were independent risk factors for the occurence of clinically relevant pancreatic fistulas after laparoscopic assisted radical gastrectomy. Conclusions:VFA increases the difficulty of laparoscopic-assisted radical gastrectomy, resulting in increased postoperative complications. VFA and operation time are independent risk factors for clinically relevant pancreatic fistula after radical gastrectomy for gastric cancer.
ABSTRACT
Objective:To investigate the related factors that affect the occurrence of severe pancreatic fistula after radical gastrectomy.Methods:The clinical data of 460 patients undergoing radical gastrectomy in The People's Hospital of Shouguang from January 2015 to January 2021 were retrospectively analyzed. These patients were divided into severe pancreatic fistula group ( n = 24) and non-severe pancreatic fistula group ( n = 436) according to whether they developed severe pancreatic fistula after surgery. Preoperative clinical data, surgical data, and abdominal drainage fluid amylase level in the first postoperative days were compared. The receiver operating characteristics (ROC) curve was used to calculate the cutoff value of abdominal drainage fluid amylase level on the 1 st and 3 rd days of developing severe pancreatic fistula after radical gastrectomy. The incidence of pancreatic fistula was compared between different amylase level groups. Multivariate logistic regression was performed to analyze the independent risk factors of severe pancreatic fistula after surgery. Results:There were significant differences in body mass index, operative time, intraoperative blood loss, peritoneal drainage fluid amylase level on the 1 st and 3 rd days after surgery, and the number of cases undergoing splenectomy between the two groups (all P < 0.05). The cutoff values of amylase level in peritoneal drainage fluid (D-AMY) on the 1 st and 3 rd days after surgery were 2 156 IU/L and 596 IU/L respectively, which had high sensitivity and specificity. On the 1 st and 3 rd days after surgery, the incidence of pancreatic fistula in the high-level amylase group was significantly higher than that in the low-level amylase group [26.2% (16/61) vs. 0.8% (3/334), χ2 = 62.82, P < 0.05). Multivariate logistic analysis showed that obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery were independent risk factors for severe pancreatic fistula, and the differences were statistically significant (all P < 0.05). Conclusion:Obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery are independent risk factors affecting the occurrence of severe pancreatic fistula. D-AMY (> 2 156 IU/L) on the 1 st day and D-AMY (> 596 IU/L) on the 3 rd day in the early postoperative days can be used as cutoff values to predict the occurrence of severe pancreatic fistula after radical gastrectomy.
ABSTRACT
Objective:To evaluate the relationship between abdominal amylase, C-reactive protein (CRP), procalcitonin (PCT) and clinically relevant pancreatic fistula in the early stage after radical gastrectomy for gastric cancer, and to explore whether they can be used as early predictors of pancreatic fistula and their accuracy, in order to help identify pancreatic fistula in the early stage after gastrectomy.Methods:The clinical data of 372 patients diagnosed as gastric cancer and underwent gastrectomy in Shouguang People′s Hospital from January 2017 to December 2021 were retrospectively analyzed, including 190 males and 182 femals, aged from 28 to 32 years old, with the average years of 63.5±10.6. The receiver operating characteristic (ROC) curves of abdominal amylase on the first day and serum CRP and procalcitonin on the third day after surgery for gastric cancer were analyzed. The ROC curve was used to determine the optimal cutoff value and the sensitivity, specificity, positive and negative predictions, and accuracy of the optimal cutoff value were calculated. Single factor and multivariate analysis were used to analyze the risk factors of pancreatic fistula after gastric cancer surgery. SPSS 25.0 software was used for statistical analysis.Results:The incidence of clinically relevant pancreatic fistula after surgery for gastric cancer was 5.37%(20/372), including 18 cases of grade B pancreatic fistula and 2 cases of grade C pancreatic fistula. The critical values of amylase on the first postoperative day of clinically relevant pancreatic fistula after surgery for gastric cancer are predicted to be 2036 U/L, serum CRP 18 mg/dL, and procalcitonin 0.85 μg/L. In univariate analysis, body mass index, abdominal amylase concentration on the 1st postoperative day, serum CRP and procalcitonin on the 3rd postoperative day were the influencing factors for the occurance of pancreatic fistula after gastric cancer surgery. Multivariate Logistic regression analysis showed that body mass index>25 kg/m 2, abdominal amylase >2036 U/L on the first postoperative day and serum CRP>18 mg/dL on the third postoperative day were the independent predictors for pancreatic fistula. The sensitivity and specificity of the combination of intraperitoneal amylase on the first day and serum CRP on the third day after surgery for gastric cancer in predicting the occurrence of clinically relevant pancreatic fistula were 87.6% and 90.4%, respectively. Conclusions:The combination of amylase in abdominal cavity on the 1st day and CRP on the 3rd day after radical gastrectomy has high sensitivity and specificity in predicting clinically related pancreatic fistula. PCT on the 3rd day after gastric cancer surgery has limited accuracy in predicting clinically related pancreatic fistula, so it is not recommended as an early prediction index of pancreatic fistula after gastric cancer surgery.

ABSTRACT
Objective To explore the effects and possible mechanism of histone deacetylase inhibitor SAHA on the interstitial fibrosis induced by diabetes.Methods The SD rats were divided into three groups:control group (Con,n=9),diabetes mellitus (DM) group (n=9) and SAHA treatment group (n=9).The diabetic rat model was established by injecting streptozotocin (STZ) through tail vein.After 8 weeks,the SAHA treatment group rats were fed with a SAHA solution (25 mg· kg-1 · d-1) by gastric gavage.After 16 weeks,all rats were sacrificed to detect relevant biochemical parameters,and observe the changes of pathomorphology in kidney.In addition,immunohistochemistry staining and Western blotting were employed to detect the protein expressions of transforming growth factor-β1 (TGF-β1),Smad2,Smad3,p-Smad2,p-Smad3,Smad7,collagen-Ⅰ and collagen-Ⅲ,respectively.Results Compared with Con group,the levels of blood glucose (BG),urinary trace albumin/urinary creatinine (ACR),triglyceride (TG) and total cholesterol (TC) in the diabetic group were all increased significantly (all P ＜ 0.05),the protein expressions of TGF-β1,p-Smad2,p-Smad3,collagen-Ⅰ and collagen-Ⅲ in kidney were all increased in diabetic group (all P ＜ 0.05),and the expression of Smad7 was significantly reduced (P ＜ 0.05).Compared with DM group,the levels of ACR was reduced,the renal fibrosis was alleviated,the protein expressions of TGF-β1,p-Smad2,p-Smad3,collagen-Ⅰ and collagen-Ⅲ in SAHA group were all decreased (all P ＜ 0.05),and the expression of Smad7 was increased significantly (P ＜ 0.05).Conclusion SAHA may restore the protein level of Smad7 by enhancing protein stability,then promote the moderate transduction of TGF-β1/Smads signaling pathway,which reduce the fibrosis of renal tubules in diabetic rats.
ABSTRACT
Objective To discuss the application value of DWI and ADC on predicting therapeutic effect of radiotherapy treatment in NPC. Methods Twenty four local recurrent cases and 38 non-recurrent cases after radiotherapy treatment in NPC were reviewed. MRI and DWI-MRI were performed at pre-radiotherapy and 3, 6, 12 months after treatment, the ADC values of the lesions were analyzed by SPSS 18.0 statistical software. ROC curves based on the ADC values were measured in 3, 6, 12 months after treatment plotted to analyze the threshold ADC value for confirming recurrence. Results The recurrent group and newly diagnosed group showed significantly high signal on DWI, while the non-recurrent group acquired low or mixed signal. The ADC values of the primary tumor in the recurrent group and the non-recurrent group were (0.709 ± 0.078) × 10-3 and (0.693 ± 0.089) × 10-3mm2/s, respectively, t=-0.717,P>0.05, respectively.The ADC values of the primary and recurrent tumor in the recurrent group were (0.730± 0.068) × 10-3mm2/s and (0.709 ± 0.078) × 10-3mm2/s, t=-1.000,P>0.05 , respectively.There were statistical differences between the recurrent group and the non-recurrent group for ADC in 3, 6, 12 months after treatment:(1.128 ± 0.179) × 10-3 and (1.358 ± 0.145) × 10-3mm2/s, t=5.567,P<0.01;(1.164 ± 0.174) and (1.450 ± 0.102) × 10-3mm2/s, t=7.310,P<0.01;(1.107 ± 0.180) × 10-3 and (1.584 ± 0.125) × 10-3mm2/s, t=11.189,P<0.01;respectively. Take 1.29 × 10-3 mm2/s,1.32 × 10-3mm2/s,1.37 × 10-3mm2/s respectively in 3, 6, 12months after treatment as the diagnostic threshold to predict tumor recurrence. The sensitive , specificity, and accuracy were (83.3%, 73.7%, 77.4%), (83.3%, 89.5%, 87.1%), (100.0%, 94.7%, 96.3%).Conclusions Both DWI and ADC value are important for diagnosing and predicting recurrent NPC after radiotherapy treatment, DWI and ADC can be used to regular follow-up after radiotherapy, to further improve the rate of early diagnosis of recurrent NPC.

Objective To explore the diagnostic value of MRE for differentiating hepatic benign and malignant tumors.Methods 36 patients with liver tumor (a total of 39 lesions,including 20 hepatocellular carcinomas,7 hemangiomas,5 cholangiocellular carcinomas,3 metastases,2 hepatic angiomyolipomas,1 carcinosarcoma,1 castleman’s disease)and 9 healthy volunteers were evaluated with MRE.The elastogram were generated with FUNCTOOL post processing program.The mean value of elasticity of hepatic malignant tumors,hepatic benign tumors,hepatic parenchyma around the malignant tumors,hepatic parenchyma around the benign tumors and the normal liver of healthy volunteers were measured and compared.Results The mean value of elasticity of malignant tumors [(7.39±1.70)kPa]was significantly higher than these of benign tumors [(4.11±0.37)kPa,P 0.05).A cutoff value of 5.08 kPa can accurately differentiate malignant tumors from benign tumors and normal liver parenchyma.Conclusion MRE could be used in diagnosis of hepatic focal tumors,which is helpful for differentiating benign and malignant liver tumors.
ABSTRACT
Objective To compare the clinical efficacy of laparoscopic repair of laparoscopic transabdominal preperitoneal(TAPP)and Lichtenstein tension-free repair herniorrhaphy in the treatment of recurrent inguinal hernia in adults,and to explore the clinical advantages of TAPP in the treatment of recurrent inguinal hernia.Methods A retrospective analysis was conducted in 54 adult patients with recurrent inguinal hernia from December 2010 to January 2015.The patients were randomly divided into TAPP group and Lichtenstein group.The operation time,intraoperative bleeding volume,postoperative hospitalization time,cost of hospitalization,postoperative complications,early postoperative pain and the recurrence of hernia were compared between the two groups.Results All patients were successfully completed surgery.The operation time of TAPP group (47.2 ±9.4)min was significantly shorter than (73.1 ±10.4)min of Lichtenstein group (t=-2.503,P=0.034).The median amount of bleeding during operation of TAPP group was 40(15 -110)ml,which was significantly less than 73(11 -130)ml in Lichtenstein group (t=-6.018,P=0.000). Postoperative hospital stay of TAPP group[(6.5 ±1.4)d]was shorter than (8.2 ±1.6)d of the Lichtenstein group (t=-2.613,P=0.028).Early postoperative pain score of TAPP group[(1.8 ±1.2)points]was better than (2.9 ± 1.4)points in Lichtenstein group (t=-7.006,P=0.000),the difference was statistically significant.However,the hospitalization cost of TAPP group[(8 842.8 ±415.2)yuan]was higher than (6 676.9 ±327.6)yuan of the Lichtenstein group,the difference was statistically significant(t=6.782,P<0.05).In TAPP group,2 cases had complications after operation,which were less than 5 cases of Lichtenstein group.Postoperative follow up ranged from 6 to 48 months,1 case of recurrence in Lichtenstein group,the recurrence rate was 3.8%.There was no recurrence in the TAPP group.Conclusion TAPP has the advantages of short operation time,less bleeding,rapid postoperative recovery,less postoperative pain and so on.It can be used as a recommended procedure for the treatment of recurrent inguinal hernia in adults.
ABSTRACT
Objective To investigate an appropriate megavoltage computed tomography ( MVCT ) protocol to guide helical tomotherapy ( HT) for multiple metastases. Methods According to the location of target volume, 48 patients with multiple metastases undergoing HT were divided into head/chest group ( n=15), head/pelvis group (n=15), and chest/pelvis group (n=18). Each target volume received MVCT scans during the treatment. The obtained MVCT images were registered to CT images and the setup errors were recorded. The CTV?PTV margins were calculated. Comparison was made by paired t test. Results In the head/chest group, there was no significant difference in the setup error in x?axis between the head and chest (-0.15±1?25 vs. -0.21±2?34, P=0?71), while the head had significantly smaller setup errors in y?and z?axis than the chest (0.73±1?22 vs. 1.56±2?54, P=0?00;0.93±1?44 vs. 2.65±1?88, P=0?00). In the head/pelvis group, the head had significantly smaller setup errors in x?, y?, and z?axis than the pelvis (-0.16±1?31 vs. -1.29±3?72, P=0?00;0.81±1?34 vs. 3.20±3?90, P=0?00;1.24±1?75 vs. 5.49±2?80, P=0?00) . In the chest/pelvis group, there were no significant differences in setup errors in x?or y?axis between the chest and pelvis (-0.25± 2?90 vs. -0.22± 3?65, P=0?06;0.35± 3?60 vs. 0.38± 3?78, P=0?87), while the chest had a significantly smaller setup error in z?axis than the pelvis (1.95±2?81 vs. 3.35± 3?05, P=0?00) . In the three groups, the CTV?PTV margins of lower target volume were reduced in three dimensions after the correction of upper target volume, in which y?axis showed the largest reduction of CTV?PTV margins (5?13 vs. 4?01;9?17 vs. 8?30;8?52 vs. 7?13). Conclusions The setup error of individual target volume should not be used for correction of the overall setup error in HT for multiple metastases with isolated target volume. An MVCT protocol that provides image?based guidance for multiple target volumes is recommended.

ABSTRACT
Objective To observe and analyze the long-term curative effects and complications for early stage thoracic esophageal cancer patients treated with external beam radiotherapy (EBRT) and 252Cf neutron brachytherapy (NBT).Methods From May 2002 to May 2012,26 patients with early stage squamous cell carcinoma who underwent EBRT and 252Cf NBT were respectively analyzed.Patients were treated 5 days per week at 2 Gy/day for a total dose of 50 Gy with EBRT.The total radiation dose to the reference point was 12-16 Gy-eq in 3-4 fractions with 4 Gy-eq/fraction with 252Cf NBT.The 1-,3-and 5-year follow-up rates were all 100 ％.Results The 1-,3-and 5-year survival rates were 95.5 ％,95.5 ％ and 83.5 ％,respectively.The early complication rates for grades 1 and 2 radiation esophagitis were 76.9 ％ (20/26) and 23.1％ (6/26),respectively.The late complication rates for grades 0 and 1 (according to the RTOG/EORTC standard) were 84.6 ％ (22/26) and 15.4 ％ (4/26),respectively.Barium esophagography after treatments confirmed that the complete response rate was 100 ％.Twenty-two patients were confirmed by endoscopy to have either normal mucosa or inflammation change.Conclusion EBRT combined with 252Cf NBT is an effective and safe treatment for early stage esophageal squamous cell carcinoma.
ABSTRACT
Objective To explore the relationship between esophageal carcinoma extensive infiltration and lesion length and 252 Cf intracavitary brachytherapy,and to evaluate its prognostic influence.Methods Thirty-two patients with esophageal carcinoma were treated by external beam and 252Cf intracavitary radiation.The patients were first treated with conventional fractionated radiation to a dose of 38 Gy over 4 weeks,with 5 daily fractions of 2 Gy per week,and then treated with external and intracavitary radiation concomitantly (4.0 Gy per fraction,once a week on every Saturday to 12 Gy in 3 fractions).The total dose of external irradiation was 50 Gy.Results The local control rate (LCR) at 1,3 and 5 years was 93.75％,76.70％ and 65.75％ in the patients with ≤5 cm lesion (NMT5 group),and 60.94％,27.08％ and 27.08％ in the patients with ＞5 cm lesion (MT5 group),respectively (x2 =7.01,P ＜ 0.05).The 1-,3-and 5-year survival rate (SR) was 93.75％,56.25％ and 43.75％ in the NMT5 group,and 75.00％,18.75％,12.50％ in the MT5 group,respectively (x2 =5.96,P ＜ 0.05).The LCR at 1,3 and 5 years was 92.31％,73.85％ and 61.54％ in the patients with ≤1.5 cm infiltration depth (NMT1.5 group),and 67.67％,35.45％ and 35.45％ in the patients with ＞ 1.5 cm infiltration depth (MT1.5 group),respectively (x2 =3.87,P ＜ 0.05).The 1-,3-and 5-year SR was 92.31％,61.54％ and 46.15％ in the NMT1.5 group,and 73.68％,21.05％ and 15.79％ in the MT1.5 group,respectively (x2 =6.24,P ＜ 0.05).LCR and SR in the patients with ≤5 cm lesion and ≤2 cm infiltration depth were significantly better than those with ＞ 5 cm lesion and ＞ 2 cm infiltration depth (x2 =10.09,7.97,P ＜ 0.05).Conclusions The patients with ≤5 cm lesion length or those with ≤ 1.5 cm infiltration depth,might become the most adaptable indication for 252 Cf intracavitary radiation.In addition,those patients with ≤2 cm infiltration depth and ≤5 cm lesion length were also suitable for 252Cf intracavitary radiation.
ABSTRACT
BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.

ABSTRACT
Objective To investigate the value of multi-slice CT in the diagnosis of gastrointestinal stromal tumor. Method CT image of 15 cases of GIST confirmed by surgical pathology were analyzed retrospectively. Re-sults The tumors originated from the stomach(n = 8), duodenum (n = 1),jejunum and ileum (n = 3), colon(n = 1), mesentery(n = 2). The main display of CT were hemorrhage,necresis and cystic change within the tumor. The en-hancement of parenchyma was clear. The enhancement of venous phase was more clear than that of arterial phase. Conclusion MSCT is a valuable examination for GIST. MSCT can precisely display the location, shape, size and en-hancement of GIST. MSCT can be worth the locating,qualitative and staging diagnosis.
